Intended Use

Hemodialysis with SyntraTM + dialyzers is indicated for patients with renal failure when conservative therapy is judged to be inadequate. It also may be indicated in the treatment of patients intoxicated with poisons or drugs.

Device Story

Syntra™ + Dialyzer is a high-permeability hemodialysis device used for extracorporeal blood treatment. It facilitates the removal of toxins and excess fluids from the blood of patients with renal failure or drug/poison intoxication. The device functions as a semi-permeable membrane filter within a hemodialysis system. It is intended for clinical use by healthcare professionals in a dialysis setting. The device provides blood-side integrity and filtration performance consistent with established hemodialysis standards, aiding in the management of renal insufficiency and acute poisoning.

Clinical Evidence

No clinical data. Bench testing only, including biological evaluation (ISO 10993-1), sterilization validation (AAMI/ISO 11137:1994), pyrogen testing (USP 24 <161>), and particulate counting (USP XXIII <788>).

Technological Characteristics

High permeability hemodialysis system. Materials meet ISO 10993-1 biological requirements. Sterilization via gamma radiation (AAMI/ISO 11137:1994). Complies with USP 24 <161> for pyrogens and USP XXIII <788> for particulates. Functional testing includes blood side integrity and manufacturing specification conformance.

Indications for Use

Indicated for patients with renal failure requiring hemodialysis when conservative therapy is inadequate, and for patients intoxicated with poisons or drugs.

Regulatory Classification

Identification

A high permeability hemodialysis system is a device intended for use as an artificial kidney system for the treatment of patients with renal failure, fluid overload, or toxemic conditions by performing such therapies as hemodialysis, hemofiltration, hemoconcentration, and hemodiafiltration. Using a hemodialyzer with a semipermeable membrane that is more permeable to water than the semipermeable membrane of the conventional hemodialysis system (§ 876.5820), the high permeability hemodialysis system removes toxins or excess fluid from the patient's blood using the principles of convection (via a high ultrafiltration rate) and/or diffusion (via a concentration gradient in dialysate). During treatment, blood is circulated from the patient through the hemodialyzer's blood compartment, while the dialysate solution flows countercurrent through the dialysate compartment. In this process, toxins and/or fluid are transferred across the membrane from the blood to the dialysate compartment. The hemodialysis delivery machine controls and monitors the parameters related to this processing, including the rate at which blood and dialysate are pumped through the system, and the rate at which fluid is removed from the patient. The high permeability hemodialysis system consists of the following devices:(1) The hemodialyzer consists of a semipermeable membrane with an in vitro ultrafiltration coefficient (K uf ) greater than 8 milliliters per hour per conventional millimeter of mercury, as measured with bovine or expired human blood, and is used with either an automated ultrafiltration controller or anther method of ultrafiltration control to prevent fluid imbalance.(2) The hemodialysis delivery machine is similar to the extracorporeal blood system and dialysate delivery system of the hemodialysis system and accessories (§ 876.5820), with the addition of an ultrafiltration controller and mechanisms that monitor and/or control such parameters as fluid balance, dialysate composition, and patient treatment parameters (e.g., blood pressure, hematocrit, urea, etc.). (3) The high permeability hemodialysis system accessories include, but are not limited to, tubing lines and various treatment related monitors (e.g., dialysate pH, blood pressure, hematocrit, and blood recirculation monitors).

Special Controls

*Classification.* Class II. The special controls for this device are FDA's:(1) “Use of International Standard ISO 10993 ‘Biological Evaluation of Medical Device—Part I: Evaluation and Testing,’ ” (2) “Guidance for the Content of 510(k)s for Conventional and High Permeability Hemodialyzers,” (3) “Guidance for Industry and CDRH Reviewers on the Content of Premarket Notifications for Hemodialysis Delivery Systems,” (4) “Guidance for the Content of Premarket Notifications for Water Purification Components and Systems for Hemodialysis,” and (5) “Guidance for Hemodialyzer Reuse Labeling.”
